Staff Software Engineer — Fintech/Blockchain Infrastructure Remote (US) | West Coast Overlap strongly Preferred

This is a staff-level opportunity with a fintech infrastructure company whose stablecoin and payments platform processes trillions in on-chain volume and operates across 180+ countries. If you're a senior engineer ready to step into a genuine staff role with meaningful equity and cross-team technical influence, this is worth your attention.

What you'll be doing

You'll lead architecture and system design across teams of 5+, own critical microservices handling real-money movement at scale, and act as a domain expert in at least one of: API design, payments processing, or blockchain. You'll help shape engineering standards, drive integration with banks and financial platforms, and contribute to a flat, high-feedback engineering culture.

What they're looking for

• 7+ years of professional software development in object-oriented languages; deep Java expertise required. Go is secondary. C#/.NET backgrounds are not a fit.
• Proven technical leadership of teams larger than 4 on architecture and system design
• Expert-level depth in at least one domain: API design, payments processing, or blockchain/Web3
• Deep experience with production-grade distributed systems, Kubernetes or ECS/EKS, RESTful API design, and cloud infrastructure
• Familiarity with Web3, smart contract business logic, and blockchain protocols — this is a real requirement at staff level, not a nice-to-have
• SQL database design and schema experience
• CS degree or equivalent

Compensation $175,000 – $250,000 base + 10–15% annual bonus + RSU grant. Total comp is flexible for the right profile.
